You can't just shoot at infinity or any other fixed focus setting and expect to get good results. Subjects that are in the range of DOF will be somewhat sharp, but not critically. You're probably getting some motion blur at that speed as well.
For shooting sports, go to a smaller stop, perhaps 5.6, and a higher shutter speed, 1/500th or more, and focus on the target. With the *istDS, you'll probably have to focus manually to nail it.
